'The Schedule referred to in these Letters Patent and making of `tie same To all whom it may concern: -pBe it known that we, ABRMI'REESE and JACOB REESE, of the city of `Pittsburg,in the county of Allegheny and State of Pennsylvania, have inventfed a new and -useful lmprovetnentin Machine for `Bolling Iron of Varying Width and Thickness; and f wedo hereby declare the following to be a full, cl'ear, and exact description thereof, reference being had `to theaccotnpanying drawing making a part of this specification, in whichi Figurel is a front elevation of our improvement, "with a suitablearrangement of dies and rolls for roll- "inghorseshoe-blanks. j i y A 3 fFigure 2 is an end view of thevertieal, and a plan i `View of the lower horizont-al rolls of tig. 1,'the same andy i 1 b Figures 3 and 4 are perspeetive'lviews of the voppo- 'te' faces of a horseshoe-blank. y l 1 Like letters indicatelike parts in each. In the manufacture ot' horseshoe-blanks, the bar C "mnstbe thickened and reduced in width at certain in- "ttervals'to form the heel; atthe toe it must be made thinner and wider; the upper face must be beveled'on the inner edge, with anulformjtaper from the toe face near the outer edge must beicreased at proper intervals, and all the parts mustfin every blank, fbe in theisame relation to each other.

J ust outside the ends of these `rolls, and with Lits axis inthe plane of their axis, `is a shaft, l, its-lower end resting ina step,m, andits rippen-end in the housingframe `m'.

`parteither way to neareaclrheeh-and the opposite Ifapart of the workbe done at one pass through flaoonsiderable waste willrbe experienced, not onlyl llhe object of` onrfflinvention is to roll horseshoeranged a metallic ring or die, the inner part a ofthe face of which is cylindrical, and the outer part a'is beveled with an outward tlarc. But the breadth of this bevel, however, tapers, as shown.

Thefaee of this ring t a is designed to form the upper face of the shoe-blank, and its'several parts are relatively shaped and proportioned, so as to produce this result. y

The cylindrical part a forms the flat face o', or the lface next the `outer edge of the shoe-blank, and the beveled part a' forms the bevel face t" of the blank, the `broadest part of the bevel a forming the broadest, part of the bevel fi', and cach Vtapering either way therefrom.

At the end, ur von the face of the next roll b', a pair of collars is adjusted, 'by which a groove o is formed, for convenience in adjusting a guide such as is described in Letters Patent grantedto Abram Reese, 23d November, 1869. v

Outside the outer collar c is arrangedv a ring or die, e, which has a cylindrical face of varying width, 'and it is so adjusted with reference to the die-ringe that the broadest parts of the two shall come opposite to each other. This ring c forms the lower face o ofthe blank.

The two rings a and c operate in the same plane, with their faces opposite each other, and between" the two the blank is rolled, with its outer edgcvagainst the collar c, which prevents the spread of the iron in that direction, so that, as the bar is reduced, it can spread only outward between the face of the bevel a' and the corresponding face of the ring e. The rings.

fas shown, are tit-ted up for lthe rolling of two blanks at each revolution.` They are fastenedzonto the rolls by keys, clamps, or in other known way.

In` the lower ring e the ereasers s are arranged at suitable intervals for forming the creases c in the blank, and Vfor `the purpose of cutting` the blanks apart a cutter, s', is 'inserted at the proper point.

lo secure the increased thickness desired in the heel, the ring-e may be flattened slightly at the cutter s', or the other ring, at thepoint corresponding thereto.

` In order to make the iron thicker and narrower at the heel, aredueing pressure must be applied on its edge,'which resultwe elect by means of' a double cam or `eccentric roll d, arranged on-the vertical shaft l, at

such point that' its operative face shall come opposite A vthe bite of the rings a ai and e. `It isalso so arranged that the face of greatest eccentrieity shall come opposite to the narrowest part off'the ring c, as shown in iig. 2, and come near enough to the collar'c t'o"swag -sl `up the bar edgewise, decrease its breadth, and increase its thickness, so as to form a heel part to the blank, oi

, `the desired form. Atgtheend oronthe face of the upper roll bis ar From the thickest and'narrowest part of thel heel,

roll d.

any desired tix-Iier can be given to the blank, forwird toward the toc, by shaping the face ofthe eccentric .roll cl accordingly. As shown, the eccentrica'. is, like What we claim as our invention, and desire to secure by Letters Patent, is-

1. The dies a a' and c, arranged on a pair of horizontal rolls, in combination with a collar c and vertical edging-roll d, substantially as described.

2. lThe subject matter of Ythe last claim, iu combination with the creasers c, substantially as described.

3. The dies a a'and e, in combination with creascrs set forth.

In testimony whereof', we, the said ABRAM RnEsn and JACOB REESE, have hereunto set our hands.
